Description

Technical Field

[0001] The present invention belongs to the technical field of substations, and particularly relates to a modular box-type substation. Background Art

[0002] A modular substation is a new type of substation in which the equipment and functions of the substation are modularly designed, produced, and assembled according to certain rules and standards. Among them, most modules are produced and assembled in a factory environment. The factory has a standardized production process, a strict quality control system, and good production conditions, which can ensure the stable and reliable production quality of the modules and reduce quality problems in on-site construction. For example, the outer shell of the module can be precisely processed and anti-corrosion treated in the factory, improving the protection level and service life of the equipment.

[0003] For example, the invention patent application with the patent application number 202211040809.8 discloses a modular box-type substation outer shell and its assembly method. Its specific components are all sheet-like structures, thus achieving the effect of being convenient for transportation, and there is no need to assemble small parts. The assembly process is simple, the assembly time is short, and the technical proficiency requirements for assembly workers are not high, solving the problems existing in the prior art.

[0004] For example, the invention patent with the patent application number 201711217253.4 discloses a modular prefabricated cabin body, a modular prefabricated cabin, and a substation; the modular prefabricated cabin body reduces the production and processing floor area, reduces the processing difficulty, improves the production efficiency, and reduces the processing cost through a flexible assembly mode, solving the transportation problem. It solves the problems of high manufacturing cost, difficult processing, and transportation in the prior art.

[0005] The above two modular substation settings overcome the on-site assembly of small parts and adopt a "sheet" structure to be combined by bolts; however, during the on-site combination process, a crane is required to lift each "sheet" for docking. During the docking process, it is greatly affected by the crane operation and the external environment, and there will be a shaking situation, resulting in difficulty in completing the docking and assembly. Summary of the Invention

[0006] In view of the above technical problems, the present invention provides a modular box-type substation, which adopts a modular structure; and lifting ropes and traction ropes are used as lifting guides between the modules, thereby reducing the splicing difficulty.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0008] A modular box-type substation, comprising a chassis module, a side plate module, and a top module;

[0009] The chassis module includes a fixed chassis and support columns. There are four support columns. Two support columns are hinged to each side of the fixed chassis. A connecting plate is fixed to the lower end of each support column, and the connecting plate is fixedly connected to the fixed chassis by bolts.

[0010] There are four side plate modules. Each of the four side plate modules includes an outer panel, a fixed frame, and a pair of connecting and positioning columns. The fixed frame and the pair of connecting and positioning columns are both fixedly connected to the outer panel. A through connection hole is provided on the connecting and positioning column. A card slot is provided on the fixed chassis. A connection pin that cooperates with the card slot is fixed to the bottom of the lifting rope. The lifting rope passes through the connection hole and extends from the bottom of the connecting and positioning column to be clamped with the fixed chassis.

[0011] The top module includes a top cover and a scraper assembly. A plug-in column that is inserted into the connection hole is fixedly connected to the bottom of the top cover. The scraper assembly is arranged on the top cover. Hoists are respectively fixed on two relatively arranged side plate modules. The scraper assembly is connected with a traction rope. The two ends of the traction rope respectively pass through the top cover, the plug-in column, and the connecting and positioning column to be fixedly connected to the corresponding hoist.

[0012] The card slot is composed of an insertion part and a clamping part. The connection pin is inserted through the insertion part and then moved to the clamping part, and the connection pin is clamped by the clamping part. A pushing assembly is provided at the card slot to move the connection pin from the clamping part to the insertion part.

[0013] The pushing assembly includes a push plate, a pull rod, and a compression spring. The push plate is arranged inside the fixed chassis. The pull rod slides through the fixed chassis and is fixedly connected to the push plate. The compression spring is sleeved outside the pull rod, and the two ends of the compression spring are respectively in contact with the push plate and the inside of the fixed chassis. The connection pin is moved from the clamping part to the insertion part by the movement of the push plate.

[0014] The push plate is fixedly connected with a wedge-shaped push block. An installation bolt hole is provided on the fixed chassis, and the installation bolt hole is located above the wedge-shaped push block.

[0015] The scraper assembly includes a guide rod and a scraper. The guide rod is fixedly connected to the top cover. The scraper is slidably connected to the guide rod. A connection ear for fixedly connecting with the traction rope is provided on the scraper.

[0016] The top module further includes a centering mechanism. The centering mechanism includes a driving frame and a centering clamping plate. The driving frame is located below the top cover and is slidably connected to the top cover. The centering clamping plate passes through the top cover and is fixedly connected to the driving frame. A limiting groove that cooperates with the scraper is provided on the centering clamping plate.

[0017] A spring plate is provided between the driving frame and the top cover, and the two ends of the spring plate are respectively hinged to the top cover and the driving frame.

[0018] The driving frame is slidably connected to the plug-in column on the top cover.

[0019] A guide pulley cooperating with the towing rope is provided on the top cover, and a limiting baffle is provided at the guide pulley.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] A lifting rope is provided. The lifting rope can pass through the connection hole and extend from the bottom of the connection positioning column to be clamped with the fixed chassis. The lifting rope and the side plate module are lifted by a crane. The lifting rope is in a straightened state, and the side plate module can move along the lifting rope, so as to complete the docking with the fixed chassis. That is, the lifting rope not only plays a role in lifting, but also can play a role in guiding docking, thereby reducing the splicing difficulty.

[0022] A detachable clamping structure is adopted between the connecting pin and the clamping groove. After the splicing of one side plate module is completed, the connecting pin and the clamping groove are separated, and then it can be reused for the installation of another side plate module.

[0023] A towing rope is provided. The towing rope passes through the connection positioning column and the plugging column and is connected with the scraper assembly; during the lifting process, the towing rope is tightened by a winch, so that during the lifting of the top cover, the towing rope is in a straightened state, and the top cover can move along the towing rope, so as to complete the docking of the top cover with each side plate module. The towing rope also plays a role in towing the movement of the scraper assembly.

[0024] A pushing component and a wedge-shaped pushing block are provided. After the side plate module and the fixed chassis are connected by bolts, the bolts cooperate with the wedge-shaped pushing block to drive the push plate to move the connecting pin from the clamping part to the inserting part, so as to realize the separation of the lifting rope and the fixed chassis. Such a structural setting can ensure that after the bolt connection between the side plate module and the fixed chassis is stable, the lifting rope is removed.

[0025] An alignment mechanism is provided. The alignment mechanism can prevent the scraper assembly from moving randomly during the installation of the top cover; a driving frame is provided. When the top cover and the side plate module are installed in place, the restriction on the scraper assembly is released. Description of the Drawings

Detailed implementation manners

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0039] As Figures 1-11 shown, a modular box-type substation includes a chassis module 1, a side plate module 2, and a top module 3.

[0040] The chassis module 1 includes a fixed chassis 10 and four support columns 11. Two support columns 11 are hinged to each side of the fixed chassis 10. At the lower end of each support column 11, a connecting plate 12 is fixed, and the connecting plate 12 is fixedly connected to the fixed chassis 10 by bolts. During transportation, each support column 11 is rotated and laid flat to reduce its height. When it is transported to the designated installation location, each support column 11 is rotated in the reverse direction to the vertical state and then fixed.

[0041] There are four side plate modules 2, specifically divided into a front side plate module, a rear side plate module, a left side plate module, and a right side plate module. Specifically: The front side plate module is provided with an openable door, and the rear side plate module is provided with corresponding ventilation holes.

[0042] The basic structures of the four side plate modules 2 are the same, and each includes an outer panel 20, a fixed frame 21, and a pair of connecting and positioning columns 22. The fixed frame 21 and the pair of connecting and positioning columns 22 are both fixedly connected to the outer panel 20. The connecting and positioning columns 22 are provided with through connection holes 23 up and down. The lifting ropes 26 can pass through the connection holes 23 and extend out from the bottom of the connecting and positioning columns 22 to be clamped with the fixed chassis 10. The fixed chassis 10 is provided with corresponding card slots 24, and the bottom of the lifting ropes 26 is fixed with corresponding connecting pins 25. Specifically: There are two lifting ropes 26, and the two lifting ropes 26 respectively pass through the corresponding connection holes 23; the upper ends of the two lifting ropes 26 are fixedly connected with a lifting plate, and the lifting plate is fixed with a lifting ear connected to the crane.

[0043] The side plate module 2 is docked with the chassis module 1 by a lifting method, and the specific operation is as follows: The two lifting ropes 26 are respectively passed through the corresponding connection holes 23, and the connecting pins 25 at the lower ends of the lifting ropes 26 are respectively clamped into the corresponding card slots 24. Then, the crane lifts the lifting plate. During the lifting process, the two lifting ropes 26 are in a taut state, forming a structure similar to a "guide rail", so that the side plate module 2 can move along the lifting ropes 26 to the position where docking is required and be lifted to the vertical state. Finally, the fixed frame 21 is fixedly connected to the fixed chassis 10 and the support columns 11 by bolts.

[0044] After the fixed connection, the connecting pin 25 is removed from the card slot 24 and pulled out from the installed side plate module 2; then, according to the above operation process, the remaining side plate modules 2 are installed.

[0045] The top module 3 includes a top cover 30 and a scraper assembly 31; for convenient lifting, lifting lugs can be provided on the top cover 30, and a crane is matched with the lifting lugs for the overall lifting of the top module 3; of course, other methods can also be used for lifting connection. The bottom of the top cover 30 is fixedly connected with a plug post 32 inserted into the connection hole 23, so as to realize the plug connection between the top cover 30 and each side plate module 2. After the plug connection, the top cover 30 and the side plate module 2 are fixedly connected by bolts. The scraper assembly 31 is arranged on the top cover 30, and hoists 33 are respectively fixed on the relatively arranged two side plate modules 2; the scraper assembly 31 is connected with a traction rope 34.

[0046] The installation process of the top module 3 is as follows: first, lift the top module 3 by a crane; then respectively pass the two ends of the traction rope 34 through the top cover 30, the plug post 32 and the connection positioning post 22 and detachably and fixedly connect them with the corresponding hoist 33. Then, tighten the traction rope 34 by the hoist 33 to make the traction rope 34 in a taut state, that is, form a structure similar to a "guide rail"; at the same time, when the crane lowers the top module 3, the hoist 33 also continues to tighten the traction rope 34; until the plug post 32 on the top cover 30 is inserted into the connection hole 23, the installation of the top module 3 can be completed.

[0047] Further, the card slot 24 is specifically composed of an insertion part 240 and a clamping part 241; the connection pin 25 is inserted through the insertion part 240 and then moved to the clamping part 241, and the connection pin 25 is clamped by the clamping part 241; a pushing component 27 is arranged at the card slot 24. After the installation between the side plate module 2 and the chassis module 1 is completed, the connection pin 25 is moved from the clamping part 241 to the insertion part 240 through the pushing component 27, and then the connection pin 25 can be removed from the card slot 24 by lifting the hanging plate upward.

[0048] Further, the pushing component 27 includes a push plate 270, a pull rod 271 and a compression spring 272; the push plate 270 is arranged in the fixed chassis 10, the pull rod 271 passes through the fixed chassis 10 and is fixedly connected with the push plate 270, and the pull rod 271 and the push plate 270 are fixedly connected by a threaded method. The compression spring 272 is sleeved outside the pull rod 271, and the two ends of the compression spring 272 are respectively in contact with the push plate 270 and the inside of the fixed chassis 10. After the installation between the side plate module 2 and the chassis module 1 is completed, pull the pull rod 271 outwards to make the push plate 270 move outwards and move the connection pin 25 from the clamping part 241 to the insertion part 240.

[0049] Further, the push plate 270 is fixedly connected with a wedge-shaped push block 273; the fixed chassis 10 is provided with mounting bolt holes 13, and the mounting bolt holes 13 are located above the wedge-shaped push block 273. That is, when the side plate module 2 is connected to the mounting bolt holes 13 by bolts, the corresponding bolts extend into the fixed chassis 10 and cooperate with the wedge-shaped push block 273; as the bolts continue to extend, they drive the wedge-shaped push block 273 to move forward continuously until the bolts are tightened, and the push plate 270 is moved outward by the wedge-shaped push block 273, moving the connecting pin 25 from the clamping portion 241 to the insertion portion 240. Through the above structural settings, the operation of pulling the pull rod 271 outward can be omitted; moreover, it can be ensured that the connecting pin 25 will move to the insertion portion 240 only after the bolts are tightened.

[0050] Further, the scraping component 31 includes a guide rod 310 and a scraper 311. The guide rod 310 is fixedly connected with the top cover 30; the scraper 311 is slidably connected with the guide rod 310; the scraper 311 is provided with a connecting ear 312 fixedly connected with the traction rope 34. The left end of the traction rope 34 is tightened by the winch 33 on the left side, and the right end of the traction rope 34 is loosened by the winch 33 on the right side; thus, the scraper 311 moves leftward along the guide rod 310; conversely, the left end of the traction rope 34 is loosened by the winch 33 on the left side, and the right end of the traction rope 34 is tightened by the winch 33 on the right side; thus, the scraper 311 moves rightward along the guide rod 310. That is, through the cooperation between the two winches 33, the left and right movement of the scraper 311 is realized, so as to clean the sundries, snow, etc. on the upper surface of the top cover 30. At the same time, through the above traction method, the traction rope 34 applies a downward pressure to the scraper 311, so that it can fit the upper surface of the top cover 30.

[0051] Specifically: a guide pulley 36 connected to the traction rope 34 is provided on the top cover 30, and a limit baffle 37 is provided at the guide pulley 36. The limit baffle 37 is fixedly connected with the top cover 30; the traction rope 34 is blocked by the limit baffle 37 to prevent the traction rope 34 from separating from the guide pulley 36.

[0052] Further, in order to prevent the traction rope 34 from driving the scraping component 31 to move when the top module 3 is installed, a centering mechanism 35 is also provided. The centering mechanism 35 includes a driving frame 350 and a centering clamping plate 351. The driving frame 350 is located below the top cover 30 and is slidably connected with the top cover 30; the centering clamping plate 351 passes through the top cover 30 and is fixedly connected with the driving frame 350. The centering clamping plate 351 is provided with a limit groove 352 that cooperates with the scraper 311.

[0053] A spring plate 353 is provided between the driving frame 350 and the top cover 30. The two ends of the spring plate 353 are respectively hinged to the top cover 30 and the driving frame 350.

[0054] Due to the action of the spring plate 353, there is a gap between the driving frame 350 and the lower surface of the top cover 30; the limiting groove 352 on the centering clamping plate 351 is clamped with the scraping plate 311, which can limit the random movement of the scraping plate 311. When the top cover 30 is inserted into the side plate module 2, the driving frame 350 is pressed down by the top cover 30, moves upward relative to the top cover 30, and drives the centering clamping plate 351 to move upward accordingly, so that the limiting groove 352 is not clamped with the scraping plate 311, that is, after the top cover 30 is installed in place, the movement of the scraping plate 311 is not restricted by the centering mechanism 35.

[0055] Specifically: The driving frame 350 is slidably connected with the insertion column 32 on the top cover 30.

[0056] Only the preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments.
